Aleksey Plekhanov updated IGNITE-27750:
---------------------------------------
Description:
Test PartitionsReservationIntegrationTest fails on teamcity with OutOfMemory
error.
Reason:
TC configured with 2g Xmx.
There are 1.6 million rows selected for each thread.
There are 10 threads executed concurrently.
Thus, the maximum number of rows in memory is 16 million.
If each row holds more than 100 bytes, then almost all available memory will be
occupied solely by query rows in this scenario.
Also, table scan is not fairly tested by this test, since plan is rewritten to
index scan on LogicalRelImplementor phase.
